The present invention comprehends the provision of a novel construction of means for firmly supporting a pneumatic inner tube for repair, thereby eliminating the necessity of holding the tube by hand, or stretching the 7 tube downwardly by the foot for such-pun pose, so that the user is afforded freedom to perform the necessary work on the tube to better advantage and in a minimum of time.

One of the chief characteristics of the present invention resides in the provision of means for the above mentioned purpose, whereby the tube is both simultaneously stretched and clamped about the support in a manner to hold that portion of the tube requiring attention, in a taut condition necessary for the proper repair of'the tube.

In carrying out the invention we provide a device of the abovementioned character which is not only simple in construction, but one with which the tube can be very quickly associated or removed therefrom as the occasion may require.

Another important object or V advantage resides in the provision of a hollow supporting member for the tube, which is also utilized to hold material and tools most frequently employed in work of this character, so that such elements are always at the command of the user.

Other objects and advantages will appear when the following detailed description read in connection with the accompanying drawing, the invention residing in the struction, combination and arrangement of parts as claimed.

In the drawing forming part of this plication like numerals of reference indicate similar parts in the several views wherein:

Figure 1 is a perspective view'of the invention showing the manner of' using the same.

Figure 2 is a top plan view partly broken away. 7

Referring to the drawing in detail, in

dicates the supporting member, for a pneu matic inner tube 11, the supporting member at 10 having associating with one end thereof a bracket plate l2 adapted to be attached to any vertical support, such as a wall, work-' bench or the like with the member 10 pro.- jecting horizontally therefrom. The supporting memberlO is preferably of hollow cylindrical contour, but it is of course to be understood that it maybe varied in size and shape, and also formed from any suitable material without departing from the inventive idea. Byreason of the hollow construction of the member 10, the latter in addition to its primary use as an inner tube support, serves as a holder for material and tools most frequently employedin the repair of inner tubes, sothat all of such elements are always within convenient reach of and at the s command of the user. In conjunction with the supporting mem ber 10, the invention provides a novel construction of means for simultaneously stretching and clamping about the member 10,, the 7i) i particular portion of the tube to be dealtwith. Consequently that portion of the tube to be repaired is held in a taut condition which is most necessary to the proper repair of the tube. 1 i A While the clamping means just referred to may vary, we preferably employ a pivotally mounted yoke-as illustrated in the specific embodiment. of the invention herein dis.-

closed. This yoke is longer than the supportso ing member 10 on which it is pivotally mounted, so that the'closed end 13 of the yoke'can be conveniently clamped to'quickly manipulate the latter. The' free ends of the opposed limbs 14 terminate in eyes 15 which receive;a pivot 16 passed through'the member 10 adjacent the bracket plate 11, the pivot projecting an appreciable distance beyond both. sides of the member 10 as illustrated. In V terposed between each eye 15 and the member 10 is a washer 17 while surrounding each end of the pivot is a coil spring 18. -These' springs bear against the eyes 15 and washers 19 held associated with the pivot by cotter pins or'the like 20. I Conseque'ntlythese '95" springs not only exert an inward pressure against the limbs 14 of the yoke, but per mit the latter to automatically adjustthemselves into clamping relation with the member 10, when the yoke is swung down '1O0 wardly over the inner tube 11- as shown in Figure 1. And this is true irrespective of the size and thickness of the particular tube supported on the member 10. 'When the yoke 5 is lowered to the position illustrated in Figure 1, that portion of the tube 11 to be dealt with is-stretched taut about the member 10 and clamped. in this condition. Due to the relative yielding movement of the limbs 14 of the yoke, any tube, irrespective of its size 7 or thickness can be effectively stretched and clamped about, the member 10, without any possibility of the limbs 14' chafling or otherwise injuringrthat portion of the tube with 'whichthey come in contact. V r The downward movement of the yoke is limitedby stop pins'2l projecting laterally from opposite sides of the member 10, butlo catedto cause'the limbs 1a to grip thetube. 11 at a point slightly below the'horizontal diameter ofthe member 10 in the final active position of the yoke. V v

In practice, the tube to be repaired is passed over the supporting member 10, with the yoke in an elevatedrposition. The lat ter is the-n swung downwardly to the posi- 1 tion illustrated in Figure 1, simultaneously stretching the tube about the member and clamping it with relation thereto. As the ;final position of the yoke is'slightly below the transverse center of the member 10, it will effectively maintain that portion of the tube beneath the transverse central plane thereof.

2. In a device of'the character described, a cylindrical tubular -member for supporting a pneumatic inner tube for repair, a yoke pivoted on said member and including yieldably 7 supported limbs for movement toward. and away from each other and utilized to stretch a portion of the tube circumferentially about said member, and stop pins projectinglate- V rally from said member in. the path of said limbs and located to cause the limbs to "frictionally clamp said portion of the tube to said member beneath the central plane thereof.

8. In a device oflthe character described, a member for supportinga pneumatic inner tube for repair, a pivot projecting from the opposite sides of the member adjacent one end thereof, a yoke including spaced limbs both pivotally and slidablymounted on said pivot, yieldable meansmounted on said pivot for exerting inward pressure against said limbs, and permitting said limbs yielding movement toward and away from each other to stretch and clamp a portion of the tube on said member.
